MathJax Is there an equivalent command to \cancel{} that I can use here?

At MMF, I have used a $\LaTeX$ command (\cancel{put factor here}) to denote the "canceling" of factors in the numerator and denominator of a rational expression for further clarity when simplifying, and I have noticed this command is not supported here.

In fact, of the 4 forums on which I participate, I have discovered that MMF is the only one that does support this command, so I am assuming it is a non-standard command and that there might be a synonymous command of which I am unaware.

Thanks and Best Regards,

Mark.

\rlap{/}x seems to work for stuff like $\displaystyle \frac{\rlap{/}x}{x\cdot \rlap{/}x} = \frac{1}{x}. $ Not sure about crossing out big stuff.

in MMF I use \not {to be factored} which misses up here .

Jameson has fixed the problem:

$\displaystyle \frac{\cancel{x}y}{\cancel{x}}=y$ where $\displaystyle x\ne0$

So, I will mark this issue solved. (Yes)

$\displaystyle \frac{\cancel{\prod a_{k}}y}{\cancel{\prod a_{k}}}=y$ where $\displaystyle \prod a_{k}\ne0.$ Works beautifully for the big stuff now indeed. Good job Jameson as always. (Rock)
